Fuel Pump Wiring
After a long time finally got the motor and box in the car, ready to run the cam in. My question is what is the proper way to wire up the fuel pump?
I want to pump to run only when the motor is running, if it stalls or anything i want the pump to stop. The pump is a mallory 140, the mallory instructions say to wire into a oil pressure switch, i've got it wired into a relay as per this;
85-Oil pressure sender
Problem is that the pumps runs as soon as key is in ignition position. The oil switch is of pressure sending type, has only only one terminal. Could this be the wrong type of sender to use, by changing this to a pressure switch would it fix the problem??????
Any info helpful. Cheers
